Design and Integration of a 2.5 MW / 5 Mwhr Energy Storage System
on the University of California, San Diego’s 42 MW Microgrid
William Torre Center for Energy Research
University of California – San Diego
September 23, 2015
UC San Diego Operates a 42 MWpeak Microgrid Campus Quick Facts
With a daily population of over 45,000, UC San Diego is the size and complexity of a small city.
As a research and medical institution, we have TWO times the energy density of commercial buildings
16 million sq. ft. of buildings, $200M/yr of building growth
Self generate 85% of annual demand •30 MW natural gas Cogen plant •2.8 MW of Fuel Cells installed •2.2 MW of Solar PV installed
UCSD’s Energy Storage Portfolio is the World’s Largest, Most Diversified University Program
8 kW Sunverge at Scripps Institute of Oceanography 108 kW, 180 kWh BMW, demonstration of application of 2nd
Life EV batteries, coupling to 330 kW PV, and Level II EV Charger
3.8 Million Gallon Thermal Energy Storage Tank Additional 1.2 Million Gallon TES awaiting commissioning
Formerly site hosted 30 kw/30 kwh PV Integrated Storage System from Sanyo/Panasonic 100 kW/ 300 kWh ZBB Flow Battery
Funded Projects To be operational 2015-16
• ARPAe CHARGES Laboratory and Microgrid Demonstration of Advanced Energy Storage Batteries ($ 3.3 M, 4 yr., ARPA-E)
